I have a set of the Kahr wood grips. The workmanship is great, the grips are very comfortable. The grips are a little thicker than the originals, and the checkering is very sharp. I find them a little less comfortable than the originals for IWB carry, but they are still easily concealed and reasonably comfortable. If you are a fan of wood, and sweating against the grips are not an issue, I highly recommend them.
Feel free to Email me with specific questions.
